Mosquitoes in Uganda: Malaria Advice for Bwindi, Yellow Fever & Tsetse (2026)

CDC recommends malaria prevention medicine for every part of Uganda, from Bwindi's cool forest to the Nile at Murchison Falls, and Uganda requires proof of yellow fever vaccination from arriving travelers 1 year and older. A separate CDC Ebola notice adds precautions and US re-entry screening, so read it before you book.

Yes. The CDC says malaria transmits in every part of Uganda and recommends prevention medicine for all of it, Bwindi's gorilla forest included. Uganda also requires proof of yellow fever vaccination from arriving travelers 1 year and older, even on a direct flight from the US. On safari, tsetse flies are the daytime biters.

Disease risk ElevatedCDC recommends malaria medicine for all of Uganda and yellow fever vaccine for travelers 9 months and older, with proof required at entry.

Bite nuisance NoticeableBwindi's cool forest tends to be light. Tsetse bite by day on savanna game drives, worst at Murchison Falls by travelers' accounts.

Check CDC's Ebola notice before you book. It has nothing to do with mosquitoes. CDC's Level 2 "Practice Enhanced Precautions" notice for the DRC and Uganda, last reviewed August 28, 2026, says CDC "recommends practicing enhanced precautions for travel to Uganda," along with parts of the DRC. US citizens and US nationals who have been in Uganda (and not in the DRC) within 21 days of arriving in the United States must enter through designated airports for enhanced screening. It also advises avoiding sick people, funerals and contact with bats and nonhuman primates, gorillas included, and watching for symptoms for 21 days after you leave.

The World Health Organization counted 20 confirmed cases in Uganda, all in Kampala District, and Uganda's outbreak ended on August 27, 2026, when WHO declared its 42-day countdown complete. In October WHO was still investigating travel links. Kenya's first case crossed into Uganda from the DRC, went to Kampala and flew from Entebbe to Nairobi on October 3, and Nigeria's imported case had traveled from Uganda. WHO's October 23 update reported no new cases in Uganda. Read the CDC notice again before you fly.

Malaria and yellow fever: two clinic questions

The CDC's wording is "CDC recommends that travelers going to Uganda take prescription medicine to prevent malaria." Transmission occurs in all areas, mostly Plasmodium falciparum resistant to chloroquine, with no exception for any area or altitude, Bwindi included. The CDC lists atovaquone-proguanil, doxycycline, mefloquine and tafenoquine.

For yellow fever, the CDC says "Vaccine is recommended for all travelers ≥9 months old," and Uganda's entry rule is "Vaccine is required for all arriving travelers ≥1 year old."

What we suggest you do with this: book a travel-medicine appointment 4–6 weeks before departure and bring the full route, park by park, plus any Rwanda or Kenya leg. One visit can settle both questions. Our malaria-zone checklist covers everything around the prescription, and Before you fly has the packing countdown.

Whatever the clinic decides, malaria mosquitoes bite from dusk to dawn. Repellent at sunset, long sleeves after dark and a net or a screened room overnight cover most of that exposure.

Tsetse on the savanna

On game drives, the biter travelers complain about is the tsetse fly. It bites in daytime, can get through thin clothing and has its strongest reputation at Murchison Falls, with Queen Elizabeth and Lake Mburo also named on forums. The CDC's Uganda page lists African sleeping sickness, spread by tsetse bites. Wear light, neutral colors on drives, not blue or black.

Bwindi's cool, high forest tends to have fewer mosquitoes than the lowland parks. Wherever you go, skip swims in Lake Victoria, Lake Bunyonyi and the Nile around Jinja, since the CDC says schistosomiasis is found in Uganda's fresh water.

When to go

The drier spells, roughly December to February and June to August, tend to be the lightest for mosquitoes and the easiest for trekking. The rains, roughly March to May and September to November, tend to bring more, with March to May the worst. The CDC's advice doesn't change with the season.

Where you're going

highland

Bwindi Impenetrable National Park

Disease risk ElevatedBite nuisance Occasional

CDC's malaria advice includes Bwindi, with no exception for altitude, though the cool forest tends to have fewer mosquitoes than the savanna parks. CDC's Ebola notice says to avoid contact with nonhuman primates, gorillas included, so keep strictly to the trekking distance rules.

safari

Murchison Falls

Hot and low along the Nile, and the park with the strongest tsetse reputation. Wear light, neutral long sleeves on game drives, then add repellent at dusk.

Inside CDC's malaria advice like the rest of the country. Forum posters name it as tsetse country too, so dress for game drives the way you would at Murchison.

Entebbe & Kampala

Disease risk ElevatedBite nuisance Noticeable

CDC makes no city exception for malaria, so the evening routine starts the night you land. All of Uganda's 2026 Ebola cases were in Kampala District, the last reported on June 21.

The Uganda kit

Spray for every evening, treated clothes for game drives.

Picaridin 20% travel sprays: odorless in the heat and quick to reapply at sundown. One 3.4 oz bottle covers about a week of daily use for one person.
Permethrin 0.5% for safari clothes: treat light, neutral long sleeves, trousers and socks at home 48 hours before you fly. It goes on fabric, never on skin.

What travelers report

Paraphrased from TripAdvisor forum threads and linked so you can read them in full. None carries a date, and bites on safari vary with the park, the season and what you wear.

Murchison Falls National Park
A traveler got about 50 bites on the legs in Murchison Falls and believed they were from tsetse flies. A reply agreed the circumstances pointed to tsetse, posters noted the flies are drawn to blue, and another advised starting antihistamines early to limit the reaction. TripAdvisor ↗
Murchison Falls and Kidepo
After a Murchison Falls and Kidepo safari, a traveler developed skin sores that turned out to contain fly larvae, which a doctor blamed on a tsetse or bot fly. Other posters disputed this and said flies laying eggs on damp, poorly dried laundry were the likely cause. TripAdvisor ↗
Uganda safari parks
Experienced posters advised avoiding blue and black clothing in favor of light creams and beiges to deter tsetse. One said there is no known tsetse repellent, while another said DEET helps but not completely. TripAdvisor ↗

One more rule outlasts the trip. Any fever during or after your trip means a doctor visit, and you tell them you were in Uganda and which parks. Malaria can show up weeks later.

Traveler questions

Do I need malaria pills for gorilla trekking in Bwindi?

The CDC recommends malaria prevention medicine for all of Uganda and makes no exception for any area or altitude, so Bwindi is covered along with Murchison Falls, Queen Elizabeth, Entebbe and Kampala. The cool forest tends to have fewer mosquitoes than the savanna parks, and the recommendation stays the same. Which medicine fits you is a call for a travel clinic, made 4–6 weeks before departure. Our malaria-zone checklist covers the rest of the preparation.

Do I need a yellow fever vaccine for Uganda?

The CDC's recommendation is "Vaccine is recommended for all travelers ≥9 months old." Uganda's entry requirement is "Vaccine is required for all arriving travelers ≥1 year old." That applies on a direct flight from the US, so carry the certificate with your passport. Settle it at the same clinic visit as the malaria question, 4–6 weeks before you fly.

Does the Ebola notice affect a gorilla trek?

CDC's Level 2 notice advises avoiding contact with nonhuman primates, gorillas included, along with bats, forest antelopes, sick people and funerals. Keep to the trekking distance rules and skip the trek if you feel ill. If you arrive back in the US within 21 days of being in Uganda, you must enter through a designated airport for enhanced screening. Read the CDC notice before you book and again before you fly.

How do I avoid tsetse flies on safari?

The CDC's Uganda page lists African sleeping sickness, spread by tsetse fly bites, and tells travelers to avoid bug bites. Tsetse bite in daytime and can get through thin clothing. Light, neutral long sleeves and trousers work better than blue and black, which have a reputation for drawing them, and treating those clothes with permethrin at home adds a layer.
